Induction hotplates works on the principle of "production of electricity/current by the magnetic field". A copper coil in under the hotplate from which alternating current is passed, which in-turn produce magnetic field. This magnetic field produces heat in 2 ways:
1. produces current in the conductive pot placed on the hotplate. (I = current)
2. these currents encounter some resistance. (R = resistance)
thus we can produce heat = I2R
Thus we saw that only conductors can get heated on a hotplate. And since steel is a conductor it gets heated. The other cookwares like glass, ceramics will not conduct any current and thus they won't get heated.

1 Why can a good blacksmith judge the temperature of a piece of heated iron by its color?
A blacksmith can judge the temperature of heated iron by its color because as the temperature increases, the iron will emit different colors of light due to its thermal radiation. This phenomenon is known as incandescence, and each color corresponds to a specific temperature range, allowing the blacksmith to estimate the temperature of the iron based on the color it is emitting.
Explain two ways that earths atmosphere gets heated?
by convection and conduction
How does the earth and it's atmosphere get heated?
The Earth's atmosphere gets heated mainly through the process of solar radiation. Energy from the sun is absorbed by the Earth's surface, which then radiates heat energy back into the atmosphere. Greenhouse gases in the atmosphere also trap some of this heat, leading to the warming of the planet.
How are currents that form in heated air similar to currents that form in heated water?
Both air and water currents that form due to heating are driven by a combination of density differences and convection. As the air or water is heated, it becomes less dense and rises, causing a flow of cooler, denser fluid to move in to replace it. This sets up a continual circulation pattern as the fluid cools, sinks, gets reheated, and rises again.
Why does the Tibetan plateau gets intensely heated up during summer?
The Tibetan Plateau gets intensely heated up during summer because of its high elevation and exposure to direct sunlight due to clear skies and low cloud cover. The thin air at high altitude also absorbs less heat, allowing more sunlight to penetrate and warm the plateau's surface. Additionally, the plateau's large landmass retains heat well, contributing to the intense heating during summer.
Why doesn't water temperature go any higher when on a hotplate?
Once water reaches its boiling point (100 degrees Celsius), the water will not get hotter. Instead, it will invest the extra energy it gets from the hotplate into converting the water from liquid to gas. The water will evaporate instead of getting hotter.
Which has higher density cold steel or hot steel?
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
How does the mantel get heated?
The mantel gets heated with hot stuff
What is use for beaker in labaratory?
to contain/hold things, particularly liquid solutions. can also be used when heating a solution on a hotplate. gets used A LOT.
What happens to steel when it gets cold?
When steel gets cold, it contracts and becomes more brittle. At extreme cold temperatures, it can become susceptible to fracturing or shattering. This is why structural engineers and material scientists consider the impact of low temperatures on steel when designing structures and equipment.
What happens when ozone is heated?
Ozone when heated gets decomposed. It decomposes into oxygen.
What happens to the ball as column A gets heated?
As column A gets heated, the ball will likely expand or increase in size due to the increase in temperature.
How air get heated in atmosphere?
air gets heated with carben dioxid and the rays of the sun
Why do we get fevers?
When your body gets over heated
What happen when gold heated?
it gets hotter
What is the meaning of men are like steel When they lose their temper they lose their worth?
Well, when steel is heated cooled rapidly by plunging it into water it becomes hard and can be sharpened to a fine edge which will not go blunt very quickly. The process is called tempering and 'tempered' steel has properties that make it more useful than 'untempered' steel. Tempered steel loses this property if it gets heated again. Thus the expression is a play on the word 'temper' - a 'pun'. A person in 'temper' is a person in a cross, hot rage. Thus for a man to lose his temper is for a man to fly into a rage. The saying = "men are like steel, when they lose their temper they lose their worth?" = means that a man in a rage has lost a valuable property (the ability to keep a cool head) just like steel looking its valuable property (its tempering) when it gets re-heated. The expression tell men that hey should not lose their 'temper'
What is induction and Placement?
PLACEMENT-Placement refers to allotement of new job to the people, job is to alloted after test and Assigning the task through people, and after the passing person gets tha job. INDUCTION-Induction is the process of identification of person to the job who has got job, when a person gets the job or selected on an appropriated job the process of indetifing to job and organisation is called Induction.
